Joomla 2.5 从外部脚本获取用户数据

我需要从 Joomla 本身之外的程序获取当前登录到 Joomla 的用户的信息。我从1.5升级到2.5，之前的功能不再起作用了。

<?php

define( '_VALID_MOS', 1 );

include_once( 'globals.php' );
require_once( 'configuration.php' );
require_once( 'includes/joomla.php' );
$option="test";
$mainframe = new mosMainFrame( $database, $option, '.' );
$mainframe->initSession();

$my = $mainframe->getUser();
$joomla_name = $my->name;
$joomla_email = $my->email;
$joomla_password = $my->password;

经过一些研究，我想出了这个：

<?php
define( '_JEXEC', 1 );
define( 'JPATH_BASE', dirname(__FILE__) );
define( 'DS', '/' );

require_once ( JPATH_BASE .DS.'configuration.php' );
require_once ( JPATH_BASE .DS.'includes'.DS.'defines.php' );
require_once ( JPATH_BASE .DS.'includes'.DS.'framework.php' );
require_once ( JPATH_BASE .DS.'libraries'.DS.'joomla'.DS.'factory.php' );

$my =& JFactory::getUser();
$joomla_name = $my->name;
$joomla_email = $my->email;
$joomla_password = $my->password;
$joomla_username = $my->username;

它不会产生任何错误，但似乎可以工作。但是，用户对象是空的。该脚本与 Joomla 安装位于同一目录中。可能是什么问题？谢谢！

解决方案：更换session_start();在你的外部脚本中

define( '_JEXEC', 1 );
define( 'JPATH_BASE', realpath(dirname(__FILE__).'/../..' ));
define( 'DS', DIRECTORY_SEPARATOR );

require_once ( JPATH_BASE .DS.'includes'.DS.'defines.php' );
require_once ( JPATH_BASE .DS.'includes'.DS.'framework.php' );
$mainframe =& JFactory::getApplication('site');
$mainframe->initialise();

一定要改变JPATH_BASE以适合您的目录结构。

更换$_SESSION[ 'name' ] = "value";在你的外部脚本中

$session =& JFactory::getSession();
$session->set('name', "value");
Now you can retrieve this session variable using:

$session =& JFactory::getSession();
echo $session->get('name');
